During one of his many adventures, Dr Saul Numen and his family, the New Men, came across an alternate Earth where the world had been devastated after the Germans won the Second World War. During this excursion the New Men found their counterparts and managed to usurp the Nazi leadership, but not before the Nazi-version of Saul Numen set in sequence a Doomsday device which destroyed not only the planet but seemingly the entire alternate reality.

Saul and his family escaped and the eminent doctor worried about the fate of the alternate world he was unable to help. He talked with an associate of his, Dr Gísladóttir, who was also the villain known as Arctic Fox. She used her knowledge of dimensions to search for any sign of the lost reality and in doing so
inadvertently brought into our reality the sole survivor: a young Jewish doctor who had been experimented upon by the Nazi regime and had been transformed into a mutated uberhuman with the ability to exude noxious gasses.

Zyklon-B was disoriented when he first arrived in our dimension (Uberworld Reality) and Dr Gísladóttir kept him isolated while Saul Numen and other scientists investigated him. They all agreed that he was a threat to society and were unable to stem the flow of gasses which seemed to be generated within his body. Saul located his counterpart in our reality but the counterpart had no uberhuman abilities. Although he was reluctant, Saul agreed to bring the two together as directed by Dr Gísladóttir.

The trauma of seeing his counterpart and knowing that his reality was erased drove Zyklon-B insane. His counterpart was also driven to the brink and fought against Saul and Dr Gísladóttir, succeeding in disabling the containment room and freeing Zyklon-B. The enraged Zyklon-B nearly killed Saul but was shunted through a dimensional portal by Dr Gísladóttir.

The two doctors parted company after that, and soon after Dr Gísladóttir
inadvertently revealed that she was Arctic Fox.

Zyklon-B disappeared, but he couldn't seem to escape Saul Numen. Every dimension he arrived in had a Saul Numen and Zyklon-B seemed destined to clash with him before being shunted to another reality. The constant shunting has driven Zyklon-B further insane while also bolstering his opinion that he is perhaps the most powerful being in creation - obviously the centre of the universe since all other realities seem to be orbiting him. He has become the only constant.

Zyklon-B has found his way into numerous dimensions and alternate realities, and has appeared in the Uberworld Reality two times. The first time after his initial exile saw him battle the New Men in Israel alongside the heroes of Cabbala. The second time he arrived at the behest of a deranged priest in Berlin and spent several months in the employ of a cult before being sent back into the dimensional melting pot by the Brotherhood and Saul Numen.

During Saul's own disappearance into the time stream, he and Zyklon-B met up in a far-flung alternate future where they were forced to team up for a time against an
unknown alien race which had seemingly enslaved Earth. The two were unable to consolidate this truce after their successful revolution as Saul was wrenched through the timeline again.

Zyklon-B has not been seen since.

Personality

Abdiel Wohlgeruch was once a timid Jewish doctor on an alternate Earth. He was captured by Saul Numen who was working for the Nazi regime and after a series of experiments and some genetic engineering, Wohlgeruch became Zyklon-B: a tortured man cursed to be a living manufacturer of poison gas.

When his reality was destroyed he was the sole survivor, a fact that drove him insane. He has since become even more unstable believing that Saul Numen is an
aberration which must be destroyed in all his incarnations, and that Zyklon-B is like some kind of universal lynch-pin, holding everything together. There is seemingly no way to convince him of any different interpretation of events and as long as those around him treat him as some kind of harbinger or messiah he is quite content to let people live. If anyone gets in his way or contradicts his beliefs, though, he will waste no time in destroying them.

Quote

"You cannot hide from me forever, Doctor Numen... and I do not care how fast you can recover from the dead. I will always be here... waiting for you and your family."

Powers

Zyklon-B has been engineered in an insidious and mostly unrevealed way. His body generates toxic gasses, similar to Zyklon-B and cyanide poisons, and he releases these constantly through his pores. He has shown an ability to manipulate this gas, and other gasses, to perform a variety of feats including flight, the generation of focused gas bolts and the ability to suffocate people simply by concentrating on restricting the flow of oxygen.

He also possesses uberhuman strength and durability, the result of experimentation and the production of such dangerous toxins in his body.

As a kind of temporal and dimensional
anomaly, Zyklon-B has the ability to shunt himself between dimensions and times although he has absolutely no control over this ability apart from the uncanny ability to arrive in areas which are close to that dimension's counterpart of Saul Numen. This shunting ability is generally triggered when Zyklon-B encounters other time travellers or extra-dimensional beings, but can also be a result of stress or simply the conclusion of a act or mission. The exact nature of this ability is unknown although Arctic Fox has done some research into it.

Appearance

Zyklon-B is a product of insidious experiments. His body is toxic but has adapted to its new condition, altering his skin to a greenish colour and his hair to a deep blue-purple. The pores in his skin are constantly emitting toxic fumes and these can sometimes form into a mist around his body. He has always worn the same costume which is a dark purple bodysuit with white belt, and bands of white around his neck, wrists, thighs and lower legs. His hair is always unkempt and he looks like he needs a week of sleep.
